If you are a time traveler you probably have noticed a few things have changed in this century. Let me tell you: We hardly post letters, we use e-mails and instant messaging to communicate. Social networks allow us to know more about our neighbours' lives, and e-commerce lets us buy anything at anytime from home. All these services and many more are in something we call Cyberspace or The Internet.

Information is good value, it has always been and the Internet is full of it now. But not only information, there are also lots of devices conected to it, such as phones, watches, glasses, vehicles, homes, fridges, TVs, and many more. It sounds crazy but listen to this, there are other devices, more important than those ones: water treatment plants, power stations, railway systems and CCTV control systems, just to give some examples. And all of them are connected to the Internet too.

Crime has also changed. With cyberspace came cybercrime: that pursuit to steal valued information and get access to devices connected to the Internet with the same old objetive: to make money. And, like in the past, it never sleeps. Some things never change!

Most people think new technologies are as secure as they are good. Unfortunately, technologies might have vulnerabilities that cyber criminals can exploit with unwanted results. Some time ago I heard of a man from London whose Facebook account was hacked: A message was posted on his wall, it asked for help from all his friends to get out from London as he was stuck with his family. A friend made a money transfer to him, or at least that is what he though he was doing, because he actually gave the money to the hacker.

Back in September 2010 two power plants were attacked in Iran, the weapon was a worm known as “Stuxnet”, that was designed to force a malfunction and delayed the nuclear plan of Iran. This is the first time no physical weapons were used to destroy a strategic target, so this is considered the first weapon of a new era of cyberwarfare. This is such an amazing subject that I definitely will tell you more about it in this blog in the future.

Sony Pictures was attacked in November 2014 by North Korean hackers to show their disapproval with a new film Sony was about to publish. The result was the biggest cyberattack over an American company ever, with huge financial and data losses.

Cybersecurity intends to make a safer cyberspace. The “the chain of security” involves so many concepts and behaviours, and everybody has a responsibility in this. This blog’s responsability is to spread the voice, a meeting point to discuss cybersecurity issues where we can all learn and share about it.

Would you leave your door wide-open when you go to work? Wouldn’t you make a new key if your key-ring was lost? Would you scream from the window if you purchased the most expensive TV on the market? Believe it or not this is happening everyday in cyberspace, and users don’t realise, unfortunately cyber criminal do.

We must all protect our lives in cyberspace as we do off-screen.

Hope you all enjoy this blog!
